KG057QV1CA-G050 is mature Kyocera 5.7-inch QVGA monochrome FSTN industrial LCD module, mass pre-installed on small industrial control equipment, desktop POS cash registers, portable pipeline fault testers and early-generation handheld analytical instruments.
220 cd/m² moderate brightness meets indoor workshop, office and retail store lighting environments. Blue negative monochrome display provides high contrast text & curve reading effect, long-term viewing less eye fatigue, ideal for displaying multi-line industrial parameter tables, real-time equipment waveform curves and fault alarm text.
